Fig. 10.24 Impact pathway for land use impacts; dashed arrows indicate impacts covered by
emission-related impact categories and by water use in the case of irrigation [adapted from
a
EC-JRC (2011)]. Land occupation will not cause changes but will contribute to prolong the
changed conditions

for use in agriculture in the Brazilian Amazon has a greater impact in terms of
number of species affected than forest clearing in an ecologically poorer European
region. Because land use impacts depend on-site-specific conditions, land use is
